问题
For my current project, I am looking for a bot building platform with the following features.
Should support the creation/updating of new/existing bot via API.
Support for intent detection from streaming audio.
Enable the hosting of multiple bot agents in a single project.
APIs to modify an existing bot/agent and save it as a new one.
So I have thoroughly researched and also developed a simple working prototype using DialogFlow. DialogFlow supports intent detection from streaming audio. But point 1 and 3 are not supported. DialogFlow at the moment does not support the creation of agent via API. And moreover, the biggest limitation is that for each GCP project, only one DialogFlow agent can be created. So let's say I have multiple agents-gcp projects created. I also have a web app running which receives audio streams via WebSocket from another external resource for intent detection. In order to direct the audio stream to the specific DialogFlow agent built, I need to resolve the credentials at runtime for that specific GCP project. I have read that I can create a service account and manage multiple GCP projects with one credential, but this is yet to try.
Also as point 4 dictates, I am also looking for a way to create new versions of an existing agent at run-time using APIs. Currently, DialogFlow supports versions and environments, but the actual purpose of this is not as I mentioned. Furthermore, this is a beta feature and not sure if it will ever be included in production.
On the other hand, I was looking into AWS Lex. Lex supports all but one of my requirement. AWS Lex at the moment does not support intent detection from the stream (I could not find any APIs for this).
So my question is how can I utilize existing DialogFlow features to fulfill my requirements? Or is there a way to detect intent from streaming audio input in AWS Lex?
回答1:
There's no mechanism for creating new Dialogflow agents via API, so parts of 1. and 4. are not possible.
For 3., as you mention, you can either manage credentials at runtime or configure a single service account with access to all of the GCP projects.
